**Application of laser sandblasting machine in mirror engraving**
With the advancement of science and technology, laser technology is increasingly used in the engraving and processing industries. As an advanced surface treatment equipment, laser sandblasting machine can not only be used for precision engraving of materials such as metal, glass, and wood, but also for sandblasting on mirror surfaces to achieve personalized artistic effects.
**Working principle of laser sandblasting machine**
Laser sandblasting machine uses high-energy laser beams to irradiate the surface of materials, causing microscopic melting, vaporization or oxidation reactions, thereby changing the surface structure of the material. For mirrors, laser beams can remove or change the mirror coating to form a mist or frosted effect, achieving complex pattern engraving.
**Precautions for using laser sandblasting machine to process mirror surface**
1. **Select appropriate laser parameters**: Different types of mirrors (such as silver mirrors, aluminum mirrors) react differently to lasers, and the laser power, speed and focal length need to be adjusted to achieve the best engraving effect.
2. **Protect the unengraved area of the mirror surface**: In order to prevent unnecessary damage to the mirror surface caused by laser scattering, a mask or protective film can be used to cover the part that does not need to be engraved.
3. **Control the engraving depth**: If the laser power is too high, it may penetrate the reflective layer of the lens surface and affect the integrity of the mirror. Therefore, a test should be performed before engraving to ensure the appropriate engraving depth.
4. **Prevent mirror reflection from affecting the laser equipment**: Since the mirror is reflective, it may affect the laser light path. The laser angle should be adjusted or special laser anti-reflection equipment should be used during operation.
